==Compatibility Tips==
=== SUGAR_BUNDLE_VERSION ===
Some earlier OLPC builds (e.g., 703) do not have a bundle version environment variable, so you need to catch an exception if you want to access the version.
try:
version = os.environ['SUGAR_BUNDLE_VERSION']
except:
version = "unknown"
=== Screen size ===
The screen size varies on different hardware platforms. If you develop in an emulator, it is worthwhile trying different sizes to make sure your activity scales properly.
Some useful utilities:
width = gtk.gdk.screen_width()
height = gtk.gdk.screen_height()
toolbox = activity.ActivityToolbox(self)
toolboxheight = toolbox._activity_toolbar.size_request()[1]
